Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid detergent composition, and more particularly to a liquid detergent composition having excellent foaming properties, creamy foam quality, and excellent rinsing properties.

[0002]

2. Description of the Related Art
Alkyl sulfate, polyoxyethylene alkyl sulfate, alkyl benzene sulfonate, α,
-Anionic surfactants such as olefin sulfonates are widely used. However, these anionic surfactants have varying degrees of skin irritation, and there is a problem that the skin becomes rough when used continuously.

On the other hand, as surfactants having low irritation, alkyl saccharide surfactants, sulfosuccinic surfactants, ether carboxylic acid surfactants, amide ether carboxylic acid surfactants and the like are known. Have been. However, although alkyl saccharide-based surfactants have high foaming properties, they have strong blemishes during washing and rinsing, and are therefore used in combination with a conditioning agent such as a cationic polymer (Japanese Patent Laid-Open No. 2-42013). Although it has been proposed, it is not technically easy to mix a large amount into a shampoo or the like. In addition, sulfosuccinic surfactants alone have poor foaming properties, and a method of using them in combination with other surfactants (Japanese Patent Laid-Open No. 2-218797) has been proposed. Often used in combination.
Furthermore, commercially available ether carboxylic acid-based surfactants and amide ether carboxylic acid-based surfactants also have poor foaming properties, and are used only as auxiliary surfactants in detergents that require high foaming properties. ing.

[0004] This amide ether carboxylic acid type surfactant is commercially available from Chem Y in Germany under the trade name of "Akipo".
In addition to the raw material amide ether, polyoxyethylene glyceryl ether, which is an impurity derived from the raw material,
Polyoxyethylene glyceryl ether carboxylic acid, inorganic salts and the like are included.

[0005] Techniques which have heretofore been known for application of amide ether carboxylic acid surfactants to detergents include amide ether carboxylic acids, polyoxyethylene alkyl sulfates, fatty acid diethanolamides, higher alcohol alkylene oxides. Detergent in which an adduct, acyl sarcosinate and the like are combined (European Patent No. 102118), and a method in which an amide ether carboxylic acid surfactant is used in combination with a polyoxyethylene alkyl sulfate (European Patent No. 215504) ), A foam bath in which an amide ether carboxylic acid starting from an oil or fat is combined with lauryl sulfate, lauryl ether sulfate, alkyl ether carboxylic acid, or a quaternary product obtained by reacting lauric acid with glycidyltrimethylammonium chloride. Agents, shampoo agents, shower agents and the like (JP-B 63-291996, JP-EP 2
No. 19893), and a detergent containing soap as a main component and an amide ether carboxylic acid or an alkyl ether carboxylate (US Pat. No. 4,865,575).

However, none of these detergents is still satisfactory in terms of foamability and rinseability.

Therefore, there has been a demand for the development of a detergent composition which is less irritating to the skin, has a high foaming property and is excellent in rinsing properties.

[0008]

Under these circumstances, the present inventors have studied a cleaning agent containing amide ether carboxylic acid and found that impurities such as polyoxyethylene glyceryl ether and polyoxyethylene glyceryl derived from raw materials were used. It was found that a foam containing a large amount of ether carboxylic acid or pure amide ether carboxylic acid itself had poor foaming properties. And as a result of further study, if the amide ether derivative mixture containing amide ether in a specific ratio and the content of the glycerin derivative is a certain ratio or less, a fatty acid or a salt thereof is used in combination,
A detergent with low irritation to the skin, high foaming property, and creamy foam quality is obtained, and the rinsability is remarkably improved by blending a specific basic substance and adjusting it to neutral to weakly alkaline. The present invention has been completed and the present invention has been completed.

That is, the present invention provides the following components (A), (B) and
The present invention relates to a liquid detergent composition containing (C) and having a pH of 7.0 to 9.3. (A) an amide ether carboxylic acid represented by the general formula (1) or a salt thereof and an amide ether represented by the general formula (2),
(1) :( 2) = 99: 1 to 1: 9 in a weight ratio of 50
An amide ether derivative mixture containing at least 5% by weight of a glycerin derivative represented by the general formula (3) and not more than 5% by weight of the solid content.

It is preferably at least 70% by weight, particularly preferably at least 80% by weight. If the total content of these components is less than 50% by weight of the solid content, the foaming properties are poor, which is not preferable.

The weight ratio of the amide ether carboxylic acid or its salt (1) and the amide ether (2) contained in the component (A) is (1) :( 2) = 99: 1 to 10:90. It is necessary that the ratio be in the range of 95: 5 to 60:40, particularly 92: 8 to 70:30. If the ratio of the amide ether (2) is less than the above range (less than 1% by weight), the foaming property is poor, and if it exceeds the above range (more than 90% by weight), the whisking and rinsing are strong, Not preferred.

Further, the content of the glycerin derivative (3) in the component (A) must be 5% by weight or less in the solid content of the component (A), and is 3% by weight or less, particularly substantially Preferably, it is not included. When the content of the glycerin derivative (3) exceeds 5% by weight in the solid content, the foaming property is remarkably reduced, which is not preferable. It is preferable that the content of the inorganic salt such as sodium chloride, which is an impurity other than the glycerin derivative (3), in the component (A) is small.

The method for producing the amide ether derivative mixture as the component (A) is not particularly limited, and it can be produced directly by reacting a part of the amide ether. It can be added later. As a method for synthesizing an amide ether derivative mixture, a method of producing an alkanolamide from a fatty acid lower alcohol ester such as a fatty acid methyl ester as a starting material, a method of producing an alkanolamide from a fat or oil as a starting material, and an alkanolamide from a fatty acid Methods and the like. Among them, a method of producing a fatty acid lower alcohol ester such as a fatty acid methyl ester as a starting material is preferable because the coloring is less and the glycerin derivative which is an impurity is not substantially contained. In the case of other methods, for example, a method in which a fat or oil having a coconut oil fatty acid composition is used as a starting material and directly converted into an alkanolamide and then subjected to alkoxylation and carboxymethylation, a large amount of a glycerin derivative derived from the fat or oil is produced and the compound (1)
And (2) are not practically preferable because the yield is low.
In the case of a method in which a fatty acid is reacted with an alkanolamine as a starting material to form an alkanolamide, the coloration is remarkable due to the high temperature of the amidation reaction, which is not preferable.
The ratio of the amide ether carboxylic acid (1) to the amide ether (2) in the amide ether derivative mixture of the component (A) is determined by the molar ratio and the mixing method when the amide ether (2) is reacted with an alkali monohaloacetate or the like. Can be adjusted by selecting the reaction conditions.

Among them, lauric acid, myristic acid or palmitic acid, or a sodium salt, a potassium salt or a triethanolamine salt thereof is preferable.

These components (B) can be used alone or in combination of two or more. The blending amount of the component (B) in the liquid detergent composition of the present invention is not particularly limited, but is preferably 0.1 to 45% by weight, particularly preferably 0.5 to 20% by weight. If the blending amount of the component (B) is less than 0.1% by weight, the creamy foam quality is lowered, and if the blending amount exceeds 45% by weight, the foaming property is lowered, which is not preferable.

Further, in the liquid detergent composition of the present invention
The mixing ratio of the components (A) and (B) is not particularly limited, but the weight ratio (A) :( B) = 99.9: 0.1 to 25:75,
Further, it is preferably 95: 5 to 60:40, and particularly preferably 95: 5 to 60:40.
If the ratio of the component (B) is less than 0.1% by weight, the foamability is poor, and if it exceeds 75% by weight, the foamability is poor, which is not preferable.

The basic substance (C) used in the present invention can be used alone or in combination of two or more. The amount of the component (C) in the liquid detergent composition of the present invention varies depending on the type of the fatty acid or its salt used, the degree of neutralization, etc., but the pH of the detergent composition is adjusted to 7.0 to 9.3. It is necessary to obtain a sufficient amount, and the molar ratio of the free fatty acid and the fatty acid salt contained in the composition is 3/7 to 0.
It is preferable to adjust it to be 1 / 9.9. When the free fatty acid is less than the above range (when the degree of neutralization is too high), the foamability, foam quality and rinsability are deteriorated.

The liquid detergent composition of the present invention has a pH of
It is necessary to be 7.0 to 9.3, but it is particularly preferable to be 7.5 to 9.0 (measurement condition: effective 5% by weight aqueous solution).
If the pH is less than 7.0, the rinsing property will be poor, and if the pH is more than 9.3, the foaming property, the foam quality and the rinsing property will be poor and the skin irritation will be strong, which is not preferable. The pH can be adjusted by adjusting the blending amount of the component (C).
